We will be happy to help you (up to 30 days from your original purchase), but to do this we must be able to find you in our system, so please click here to send us an email with the name and email address used during your Credit Aid purchase (and an order number so we can look up your order information) . Please do send us correct info, because we really do check.  Otherwise, if you did not buy a backup CD from us we recommend making one yourself (of your setup file).  The setup file and your activation key are the product you have purchased and received from us.  It is up to you to keep a safe copy in case you ever need to reinstall.  It takes less than a minute to make a backup CD.  Please protect your software investment and make a backup copy.
